In ore deposits, the commercially valueless material in which ore is found is known as what?

Explanation:
In ore deposits, the material that surrounds the valuable ore but has little or no economic value is called gangue. This surrounding rock and nonspecific minerals must be separated from the ore during processing in order to concentrate the valuable mineral. The option that defines the valueless material in which the ore is found matches this concept directly, which is why it’s the best choice. The other options refer to the ore mineral itself or to processing steps, not to the term for the surrounding waste material.
